Monday : x
tuesday : 3x
wednesday : 3x - 20 = 40
thursday: 20

3x - 20 = 40
3x = 40 + 20
3x = 60
x = 60/3
x = 20

monday : 20 minutes
tuesday : 3x....3(20) = 60 minutes
wednesday : 40 minutes
thursday: 20
for a total of : 140 minutes <===

Answer:

Like terms are numbers with or without variables that have the same variables.

Step-by-step explanation:

5x and 3x are like terms because they have the same variable.

5x and 3y are not like terms because the variables are different.

To combine them, just add or subtract them. You cannot combine non-like terms!
